The largest genus, Ranunculus, comprises the buttercups and crowfoots, names often used interchangeably. Found throughout arctic, north temperate, and alpine regions, with species in the Andes and in subantarctic areas, this genus is characterized by glossy yellow flowers (hence the name buttercup) and deeply cut leaves (supposedly resembling crows' feet). Like some other members of the family, species of this genus contain an acrid juice that makes them unpalatable for livestock and in some species poisonous. A dozen or more species are common in every part of the United States. Among those cultivated for garden and cut flowers are some double-blossomed Old World species, e.g., the turban, or Persian, buttercup (R. asiaticus), valued for the variety of its colors (all but blue), and the creeping buttercup (R. repens), native to both North America and Europe.

the popular name for certain herbaceous plants, predominantly with yellow flowers. Plants of the genus Ranunculus, primarily the species Ranunculus acris, are most often called buttercups. R. acris is a perennial, measuring 20–80 cm. tall, with a hairy stem and generally digitipartite leaves. The flowers are golden-yellow, on long peduncles; they bloom at the beginning of the summer. R. acris grows in the temperate zone of Eurasia; in the USSR it is found in meadows, forest glades, brushwood, and forests in the European USSR, Western Siberia, and Middle Asia. It is poisonous: the juice produces severe burns on the skin and causes tearing and sharp pain in the eyes. The buttercup is a meadow weed, rarely eaten by cattle.
